I have recently purchased an A3 1.6 SE (1998). The dinky wheels need to go! I have seen two A3's with 19" wheels on but can not find the driver to ask for details. I want to know what is the maximum i can drop the A3 with 19" wheels on without causing the wheels to scrape on the arches. I've read some views concerning the ride quality but can it really be that bad? any views would be appreciated.
